Deactivating Autoptimize wordpress plugin breaks the website styles

The Autoptimize WordPress plugin was installed before for caching.
But now I want to switch to another cache plugin.SO when I de active the Autoptimize plugin the site is breaking.

I Have tried the following things

  • Cleared server cache
  • Removed /wp-content/cache/autoptimize
  • Cleared cache through php code.
  • Completely deleted plugin after deactivating.

But none of them could move forward me to the goal.
